I will pick the most probable answer which is 'yes'. Your profile has a BP logo, and the BP oil spill which happened recently was mostly affecting America. It is "British Petroleum" but has little to do with Brittain anymore. You are proficient in the English language and took some issue with someone who had imperfect use of it, so that is suggestive that it is your first language and that you are from an English speaking country. The USA has the largest portion of English speaking internet users, so it is most likely. You also have a good degree of knowledge of American pop-culture, though seeming as how America's pop-culture is everywhere, this doesn't really say much.

So all in all, I think it is likely that you are American.
